Description

A liquid phase hydrogenation reactor

technical field

The utility model belongs to the technical field of chemical equipment, in particular to a liquid-phase hydrogenation reactor.

Background technique

The hydrogenation reactor is one of the important equipment in the chemical industry. At present, there are two defects in the use of the hydrogenation reactor: 1. The structure is complex, and there are defects such as unsatisfactory operation reliability, short service life, and low reaction efficiency. 2. Originally, heat transfer oil was used as the heat exchange medium. The heat transfer oil enters from the top of the hydrogenation reactor, forms a convection flow with the rising material for heat exchange, and flows out from the middle to take away a large amount of reaction heat. In this process, the heat transfer oil cannot completely fill the reactor. , leading to uneven temperature distribution in the upper and lower parts, which cannot play the best catalytic effect. If the temperature is lower than the reaction temperature, the catalyst will lose its catalytic effect, resulting in a decrease in the utilization rate of raw materials and a reduction in product quality, which needs further improvement.
